15 Part A

You use the FOIL rule to get (x+6)(x+19) = x^2 + 25x + 114. So it appears you're a bit on the right track, but you forgot to multiply 6 and 19 to get 114.

That polynomial represents the area of the pool plus the area of the deck around the pool. The area of the pool only is x(x+13) = x^2 + 13x.

Subtract the two polynomials to get

(x^2 + 25x + 114) - (x^2 + 13x)

x^2 + 25x + 114 - x^2 - 13x

(x^2 - x^2) + (25x - 13x) + 114

0x^2 + 12x + 114

0 + 12x + 114

12x + 114

Therefore, the area of the deck only is represented by the expression 12x+114

15 Part B

x = width of the pool

Plug x = 13 into the expression we found for part A

area of deck only = 12x + 114

area of deck only = 12*13 + 114

area of deck only = 156 + 114

area of deck only = 270

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
